Procedures can return results in the form of a single row of data, or multiple rows. Results consisting of a single row of data can be passed back as arguments to the procedure. Results consisting of multiple rows of data are passed back as result sets. Procedures can also return a single value given in the RETURN statement.
For simple examples of how to return results from procedures, see Introduction to procedures.
